IA 18's air space and amp usage??

[Retroaudio 0]

I have 4 INCRIMINATOR AUDIO DEATH PENALTY 18"s I need to know the air space ported for these can't seem to find it on site and want to get it just right.

Also I was planning on using a US AMPS VLX-400 to push them do you think I need more for all 4? I have the Rockford 4000w but not sure about running 2 different amps on 4 subs that will be sharing a ported box. I am looking for another VLX-400 right now, it says at 1/4 OHMS it runs 5200w RMS should that be ok for the 4 of them.

I am looking to go to SPL comps so I want to be sure I get it right first with the amps to the speakers to the air space.
